Q: What is the maximum allowable speed of the PV7 series pumps?
A: The maximum rated speed varies with displacement; small-displacement models (≤20 cm³/rev) can reach up to 3000 rpm, while large-displacement models are generally limited to 1800-2500 rpm; refer to the product manual for specific models.
Q: What oil cleanliness level is required for PV7 series pumps?
A: The recommended oil cleanliness level is ISO 4406 Class 18/15 or higher; regular oil filtration and tank cleaning are required to prevent wear of internal components caused by particle contaminants.
Q: How to install the PV7 series pump correctly?
A: Mount the pump on a rigid base to reduce vibration; align the pump shaft with the motor shaft (coaxiality error ≤0.1 mm), use flexible couplings for connection, and ensure the suction port is lower than the oil level in the tank or use a charge pump for auxiliary suction in case of high installation positions.
Q: What should be noted when starting the PV7 series pump for the first time?
A: Fill the pump with hydraulic oil manually before startup, vent the air in the suction and discharge pipelines, start the motor at low speed for 1-2 minutes, check for leaks and abnormal noise, and gradually increase the speed and pressure to rated values.
Q: Can the PV7 series pumps be used in high-altitude or low-temperature environments?
A: For low-temperature environments (below 10 °C), select low-temperature hydraulic oil to ensure fluidity; for high-altitude environments with low air pressure, pay attention to strengthening the sealing of the suction side to prevent cavitation.
